A flotilla of witches and wizards trades broomsticks for kayaks during this playful Halloween paddle along Buffalo Bayou. Costumed participants launch from Allen's Landing for a free 3.5-mile group journey through Houston's historic waterway, creating a scene that is equal parts outdoor adventure and floating costume parade. Bring your own suitable watercraft or arrange a rental, dress for the theme, and prepare for a memorable view of downtown from water level.
